MCP6441/2/4
5.0 DESIGN AIDS
Microchip provides the basic design tools needed for
the MCP6441/2/4 op amp.
5.1 SPICE Macro Model
The latest SPICE macro model for the MCP6441/2/4
op amp is available on the Microchip web site at
www.microchip.com. The model was written and tested
in the official OrCAD (Cadence
®
) owned PSpice
®
. For
the other simulators, translation may be required.
The model covers a wide aspect of the op amp's
electrical specifications. Not only does the model cover
voltage, current and resistance of the op amp, but it
also covers the temperature and the noise effects on
the behavior of the op amp. The model has not been
verified outside of the specification range listed in the
op amp data sheet. The model behaviors under these
conditions cannot ensure it will match the actual op
amp performance.
Moreover, the model is intended to be an initial design
tool. Bench testing is a very important part of any
design and cannot be replaced with simulations. Also,
simulation results using this macro model need to be
validated by comparing them to the data sheet
specifications and characteristic curves.
5.2 FilterLab
®
Software
Microchip’s FilterLab software is an innovative software
tool that simplifies analog active filter design using op
amps. Available at no cost from the Microchip web site
at www.microchip.com/filterlab, the FilterLab design
tool provides full schematic diagrams of the filter circuit
with component values. It also outputs the filter circuit
in SPICE format, which can be used with the macro
model to simulate the actual filter performance.
5.3 Microchip Advanced Part Selector
(MAPS)
MAPS is a software tool that helps semiconductor
professionals efficiently identify the Microchip devices
that fit a particular design requirement. Available at no
cost from the Microchip website at
www.microchip.com/ maps, the MAPS is an overall
selection tool for Microchip’s product portfolio that
includes Analog, Memory, MCUs and DSCs. Using this
tool, you can define a filter to sort features for a
parametric search of devices and export side-by-side
technical comparison reports. Helpful links are also
provided for Data Sheets, Purchase and Sampling of
Microchip parts.
5.4 Analog Demonstration and
Evaluation Boards
